The 6th and 7th edition setup guides, however, have this in them:
The big disk drivers (rp.c and hp.c)
have partition tables in them which you
may want to experiment with.
which dates from March, 1975 and seems to be in /usr/start/start in the

lets you define logical disks, which are subsets of

it seems that at least one part of Digital used partitions as we now know
it in September 1984. I wonder if AT&T Unix Seventh edition also called
them partitions?
